How To Switch To RCS Messaging | Richer Text And Media

Switching to RCS messaging upgrades plain texts into richer chats with read receipts, typing indicators, and high-quality photo and video sharing.

RCS messaging turns the plain text box on your phone into something that feels far closer to a modern chat app. You get higher quality photos, smoother group conversations, and status signals that show when messages are delivered or read. The good news: on most recent Android phones, and on iPhones with newer iOS versions, you can switch to RCS in a few steps.

This guide walks you through how to switch to RCS messaging on Android and iPhone, how to check if your mobile plan works with it, and what to do when the RCS toggle refuses to cooperate. By the end, you should know exactly which settings to open, what each status line means, and when your chats will still fall back to SMS.

What RCS Messaging Changes Compared To SMS

RCS, short for Rich Communication Services, is a modern messaging standard created through the GSMA’s Universal Profile work. Instead of sending short text segments with tiny photo limits, RCS lets phones trade messages, photos, videos, voice clips, and files over data in a more flexible way.

On the surface, RCS looks like “better SMS.” Under the hood, it adds features that you usually associate with chat apps:

Typing indicators — You can see when the other person is writing a message.
Read receipts — You know when a message has been opened, not just delivered.
Higher quality media — Photos and videos can go through with far less compression than MMS.
Improved group chat — People can join, leave, and react in a way that feels closer to dedicated chat apps.
Wi-Fi and data use — Messages can send over mobile data or Wi-Fi instead of using only cellular text channels.

To make sure phones and carriers work together, the GSMA’s Universal Profile standard defines the feature set that RCS devices follow. Many mobile networks and device makers now build against that profile, which is why RCS chats can work across brands and across countries when everything lines up.

Switching To RCS Messaging On Android

On Android, Google Messages has become the main way to use RCS messaging. Many Samsung phones still ship with Samsung Messages as well, and some networks keep RCS options there too. The most stable path on current Android phones is usually Google Messages, since it can handle RCS both through your carrier and through Google’s own RCS backend.

Use Google Messages For RCS Chats

Google’s own help pages outline the basic steps to turn on RCS in Google Messages. The flow is short, as long as your carrier and region allow it.

Install Or Update Google Messages — Open the Play Store, search for “Google Messages,” and tap Update or Install.
Set Google Messages As The Default SMS App — Open Google Messages, accept any prompt that asks to make it your default, or change it in Settings > Apps > Default apps > SMS app.
Open RCS Chat Settings — In Google Messages, tap your profile picture or initial in the top right, then tap Messages settings and choose RCS chats (sometimes labeled Chat features).
Turn RCS Chats On — Turn on the main toggle for RCS chats and confirm your phone number if asked.
Wait For “Connected” Status — Under “Status,” look for wording such as “Connected.” Activation can take a few minutes, especially right after a SIM change.

If you want to dig deeper into the official instructions, Google’s own help page on how to turn on RCS chats in Google Messages matches these steps and includes options for read receipts and typing indicators.

Turn On RCS In Samsung Messages (When Available)

Some Samsung phones still include RCS options directly inside Samsung Messages, especially recent Galaxy S models with current carrier firmware. The exact labels differ by carrier, so you may see “Chat features,” “Chat settings,” or “Advanced messaging.”

Open Samsung Messages — Tap the standard Messages icon on your Samsung home screen or app drawer.
Enter The Settings Menu — Tap the three-dot menu in the top corner, then tap Settings.
Look For Chat Or Advanced Options — Open entries such as Chat settings, Chat features, or Advanced messaging.
Enable RCS Or Chat Features — Turn on any switch that mentions “RCS,” “Chat,” or “Advanced messaging” for your phone number.

On some networks, Samsung Messages only offers these RCS options if your carrier still runs its own RCS platform. If you do not see any chat-related switches at all, or messages never show chat status lines, switching to Google Messages usually gives a smoother RCS experience on Samsung phones.

Confirm That RCS Messaging Is Active

Once you switch to RCS messaging on Android, you can confirm that it actually works instead of falling back to classic SMS or MMS.

Check Chat Status In A Thread — Open a conversation with another Android user who also runs RCS, send a message, and look for “Sent via RCS” style lines near the last message.
Look For Read Receipts — When both sides have read receipts enabled, you should see delivered and read labels under messages.
Send A Larger Photo — Attach a high-resolution photo; if it sends quickly without shrinking to the tiny size you are used to from MMS, RCS is likely doing the work.

If a chat partner still has SMS-only service, your phone will quietly drop back to SMS or MMS for that thread, even when RCS is ready on your end.

Turning On RCS Messaging On iPhone

Apple added RCS messaging to the Messages app for iPhone users with iOS 18 and later. RCS messages show up as green bubbles, just like SMS and MMS, but they gain many of the richer features when the person on the other side can handle RCS as well.

Apple’s own instructions explain it in a short sequence through the Settings app. The wording may shift slightly between iOS versions, yet the general path stays the same.

Check Your iOS Version — On your iPhone, open Settings, tap General, then tap Software Update to make sure you are on iOS 18 or later.
Open Messages Settings — In the main Settings list, scroll down, tap Apps, then tap Messages.
Find The RCS Messaging Toggle — Inside Messages settings, look for an item labeled RCS Messaging.
Turn RCS Messaging On — Tap the switch so it turns on; if a prompt asks you to confirm your phone number or carrier, follow those steps.
Wait For Activation — RCS may take a short while to start working as the phone and network sync up.

Apple notes on its own help page for RCS messaging on iPhone that you need both an eligible iOS version and a mobile plan from a carrier that offers RCS on iPhone. If you run through the steps above and never see an RCS option in the Messages settings, either your phone is not on a new enough iOS release or your carrier has not rolled out RCS for iPhone lines yet.

Once RCS is active, texts to Android phones that also use RCS should show the richer features. Texts to older devices, landlines, or feature phones still fall back to standard SMS or MMS with the same green bubble color.

Check If Your Phone And Carrier Work With RCS

RCS messaging relies on three pieces all lining up: your phone, your mobile network, and the app you use for texting. If any one of those does not offer RCS, you will only see regular SMS and MMS.

Basic Checks Before You Switch

Confirm Data Access — Make sure mobile data or Wi-Fi works by opening a website or another online app.
Use A Recent Phone — Most modern Android phones and iPhones on current software versions can run RCS; very old devices may not.
Update System Software — Install pending Android or iOS updates so you have current RCS components.
Update Your Messaging App — Update Google Messages, Samsung Messages, or iOS Messages from the official store where relevant.

Carrier And Region Compatibility

Many carriers across the world now allow RCS messaging, especially those that follow the GSMA Universal Profile. Some networks still limit RCS or only enable it in certain markets. On Android, Google can also provide RCS directly through its own RCS backend in regions where carriers have not rolled out their own platform yet, which broadens coverage even more.

On iPhone, RCS messaging depends entirely on your carrier’s setup for iOS lines. That is why you need both a new iOS version and a mobile plan that lists RCS among its features before the toggle appears under Messages.

Fixing Common RCS Switch Problems

Sometimes you flip the RCS switch and nothing seems to change. Status lines stay stuck on “Setting up” or your chats keep sending as SMS even with all the right toggles in place. These are the most common roadblocks and quick fixes that usually bring RCS back into line.

RCS Status Stuck On “Setting Up” Or “Connecting”

Toggle RCS Off And Back On — In Google Messages or your phone’s Messages settings, turn the RCS switch off, wait a few seconds, then turn it on again.
Check Phone Number In Settings — In Google Messages, open Messages settings > RCS chats and confirm that the shown number matches your active SIM.
Switch From Wi-Fi To Mobile Data — Turn off Wi-Fi for a short while and let the phone register RCS over mobile data.
Restart The Phone — Hold the power button, restart, then check the RCS status again once the phone reconnects to the network.

Google’s RCS help pages also mention that if you recently moved your SIM to a new device, the old phone might still think it owns the RCS registration. Turning RCS off on the previous device, waiting a moment, and then turning it on only on the new one often clears that conflict.

Messages Still Send As SMS Instead Of RCS

Confirm The Other Person Has RCS — Ask if they use Google Messages or another RCS-capable app and whether RCS is turned on for their line.
Start A New Chat Thread — Delete the old SMS thread or simply start a new conversation; sometimes the app only checks RCS capability when a thread begins.
Check Per-Chat Settings — Some apps have per-conversation settings that can force SMS; open the chat’s menu and confirm you did not disable chat features there.
Look For Roaming Or Weak Signal — When the phone drops to basic coverage or strict roaming, RCS may pause and bounce messages back to SMS.

Switching Phones And Losing RCS

RCS messaging is tied to both your number and your current device. When you switch phones, RCS registration can lag behind if the old phone still holds an active session.

Turn Off RCS On The Old Device — Before moving your SIM, open the messaging app on your old phone and turn off its RCS or chat features.
Disable Web Or Linked Sessions — If you used web or desktop versions of your messaging app, sign out there to avoid stale RCS sessions.
Re-enable RCS On The New Phone — After you insert the SIM and activate service, turn on RCS again in Google Messages or the relevant settings menu.

If messages still fail to arrive, use the “Reset chat features” or “Troubleshoot RCS” options where available in your messaging app’s settings. These tools clear cached registrations so the phone can start fresh with the RCS network.

SMS Vs RCS Messaging At A Glance

This short table shows how classic SMS or MMS compares with modern RCS messaging for the things people usually care about in everyday chats.

Feature	SMS / MMS	RCS Messaging
Message Transport	Cellular text channels only	Mobile data or Wi-Fi
Media Quality	Small, heavily compressed images and video	Higher resolution photos and video with less compression
Typing Indicators	Not available	Shows when the other person is writing
Read Receipts	Only through some carrier add-ons	Standard option in RCS chats when both sides enable it
Group Chats	Basic; often turns to separate MMS threads	Richer groups with better membership control
Cross-Platform Reach	Works with nearly any phone line	Works when both sides have RCS-capable phones and plans

Privacy, Data Use, And When To Turn RCS Off

Switching to RCS messaging brings more features, yet it also changes how your messages move through networks. Some carriers enable stronger security layers, while others might limit certain options. RCS messaging can also draw more data than bare-bones SMS, since photos and videos stay larger.

What Happens To Your Data

RCS Uses Data Instead Of Text Buckets — Messages use mobile data or Wi-Fi, so very strict data caps can feel tighter when you send media often.
Encryption Rules Vary — Some RCS setups add end-to-end protection in certain cases; others rely on transport encryption between phone and server only.
Network Features May Differ — Typing indicators, read receipts, and unsend options may not appear on every carrier or app combination.

RCS messaging still works alongside SMS and MMS. If a message cannot go through using RCS for any reason, your phone can usually drop back to the older methods, depending on how you set up the “resend as SMS” options in your messaging app.

When Turning RCS Off Makes Sense

Very Tight Data Plans — If you run with only a small data package and send lots of media through text, sticking to MMS with strict limits may keep usage lower.
Trips With Weak Coverage — In areas where data coverage is poor but basic text still works, turning off RCS temporarily can keep messages simpler and more reliable.
Switching SIMs Often — People who swap SIMs or phones frequently may prefer to leave RCS off to avoid re-activation delays each time.

You can always turn RCS off in the same RCS or chat settings menu where you turned it on. If you later decide to return to richer chats, flipping the switch back on usually revives the previous behavior without any extra setup.

Simple Next Steps For Better Chats

Switching to RCS messaging is mostly about finding the right switch in the right app and letting your phone talk to the network for a few minutes. On Android, that usually means Google Messages with RCS chats turned on. On iPhone, it means a recent iOS version and the RCS Messaging toggle in the Messages section of the Settings app.

If you follow the steps above and still do not see RCS options, then your carrier or current region likely has not rolled it out yet. In that case, your phone will keep using SMS and MMS as usual, and you can check again after a later software or carrier update. When all the pieces line up, though, switching to RCS makes everyday text conversations feel cleaner, clearer, and more flexible without forcing either side to install a separate chat app.
